DESCRIPTION:
A vulnerability has been discovered in the User Photo component for
WordPress, which can be exploited by malicious users to compromise a
vulnerable system.

validating uploaded file types, which can be exploited to e.g.
execute arbitrary PHP code by uploading a specially crafted PHP
file.

The vulnerability is confirmed in version 0.9.4. Prior versions may
also be affected.
